on passengers side replaced the one behind the cat converter it looked original and very hard to get too, one in front looks new as well as driver side looks new. but your right just because it looks new dosen't mean it works. brain fart i'll change that one two.

get h64 oxy sensor too lean.
You have a O2 each side so there are separate error codes for each one
DTC 64 -
Bank 2 (Right Front) Heated Oxygen Sensor (HO2S) #1 Circuit (Lean Exhaust Indicated)

Also be aware a error code is for a system fault , which includes the power supply , wiring , connections and grounds;
not just that the item in that system is actually faulty
